Template:Short description Template:Chembox

Cuneane (Template:Ety[1]) is a saturated hydrocarbon with the formula Template:Chem2 and a 3D structure resembling a wedge, hence the name. Cuneane may be produced from cubane by metal-ion-catalyzed σ-bond rearrangement.[2][3] Similar reactions are known for Template:Chem name (Template:Chem2) and bishomocubane (Template:Chem2).[4][5]

Molecular geometry

The carbon atoms in the cuneane molecule form a hexahedron with point group C2v. The cuneane molecule has three kinds of equivalent carbon atoms (A, B, C), which have also been confirmed by NMR.[6] The molecular graph of the carbon skeleton of cuneane is a regular graph with non-equivalent groups of vertices, and so it is a very important test object for different algorithms of mathematical chemistry.[7][8]

Derivatives

Some cuneane derivatives have liquid crystal properties.[9]
